Installation Instructions series Non-Hold Open Models Adjustable size : 1(BF) thru 6 Optional Feature : Delayed Action An Incorrectly installed or improperly adjusted door closer can cause property damage or personal injury. these installations should be followed to avoid the possibility of misapplication or maladjustment. Read and follow instructions carefully. Note : Use this instruction sheet for installation sequence and closer adjustments only. Door should be hung on ball bearing or anti-friction hinge. A separate door stop is recommended. Door and frame must be properly reinforced. Adjusting closing time speed between 3 and 7 seconds from 90º ~ 0º. These door closers should be installed on the exposed side (weather side) of exterior doors.

series Installation Instructions Regular Arm Installation Diagram A 1. Select degree of opening from table and use template dimensions shown in above, mark six (6) holes on door for door closer and two (2) holes on frame for arm shoe. 2. Drill pilot holes in door and frame for #14 all-purpose screws or drill and tap for 1/4-20 machine screws. 3. Install adjustable forearm/arm shoe assembly to frame using screws provided. 4. Install main arm to top pinion shaft using screws provided. 5. Mount closer on door using screws provided. SPEED ADJUSTING VALVES MUST BE POSITIONED TOWARD HINGE SIDE. 6. Adjust length of adjustable forearm so that adjustable forearm is perpendicular to frame when assembled to preloaded main arm (illustration below) Secure forearm to main arm with screw provided. 7. Snap pinion cap over shaft at bottom of closer. (When using full cover. pinion cap is not necessary) 8. Adjust closing speed, back check control and spring power of door, following instructions as shown page 5. 2

Adjust closing speed, back control and spring power of door, following instructions as shown page5. 4
series Installation Instructions Adjustment Chart CLOSING SPEED CONTROL E: Closing arcs ("CLOSE" and "LATCH") are controlled by two (2) separate speed adjusting valves. Adjust the CLOSING speed first, and then adjust the LATCHING speed. 1. "CLOSING" speed adjustment is accomplished by full rotations of the speed adjusting valve. -Turn the speed adjusting valve CLOCKWISE for a SLOWER SWEEP arc closing speed. -Turn the speed adjusting valve COUNTER-CLOCKWISE for a FASTER CLOSE arc closing speed. 2. "LATCH" speed adjustment is same manner as. ("CLOSE" ) CAUTION!! Do not turn speed adjusting valve more than two(2) full turns counterclockwise from its order not back the valves out of closer or a leak will result. BACK CHECK CONTROL To increase back check intensity, turn back check Control valve clockwise. To decrease back check intensity, turn back check control valve anticlockwise. SPRING POWER CONTROL To increase opening force and closing force, turn the spring adjusting nut clockwise. To decrease opening force and closing force, turn the spring adjusting nut counter clockwise. DOOR CLOSER SIZE 900-BC/DA (SIZE: 1/2 6) HOW TO ADJUST SPRING POWER Be noted that series are set down as door closer size 3 from factory. EX: Size 2 closer can be made by rotating spring adjusting nut anti-clockwise 3 turns. Because it was set down as size 3 from the factory originally also in a same way, Size 6 closer can be made by rotating spring adjusting clockwise 9 turns. 900-BF/BF.DA 900-BC/DA (SIZE: 1/2 4) (SIZE: 1/2 6) CLOCKWISE TURNS OF ADJUSTING NUT 900-BF/BF.DA (SIZE: 1/2 4) INTERIOR APPLICABLE DOOR SIZE EXTERIOR (SWING OUT) APPLICABLE DOOR WEIGHT E: MAXIMUM ADJUSTMENT IS APPROXIMATELY 10 TURNS.

When these series of door closers are installed and adjusted to confirm to ADA reduced opening force requirements (5 lbs max.) for Interior doors, they may not have adequate closing force to reliably close and latch door. Power adjustments charted on this page are recommended where possible, to ensure proper door control 5
